Title: Sound reproducing unit
IPC: G11B33/06
Filed: 1975-05-20
Abstract: 1507313 Gramophone HASBRO INDUSTRIES Inc 20 May 1975 [20 May 1974] 54201/74 Heading G5R A spring wound gramophone particularly for use with toys includes an articulated link 114 between pick-up stylus 108 and the apex of speaker cone 6 and inner and outer annular shaped records, each including a plurality of tracks whereby randomly selected tracks on the records can be played back in sequence. Pick-up arm 96 is of plastics material and is formed with flexible hinge portions at 100 and 106. The arm includes stylus 108 disposed directly below hinge 106 and spring member 102 which acts to urge the stylus into contact with a record. A cup at the free end of an extension 104 of the pick-up arm forms a universal joint with a ball at one end of rod 114 and a similar joint couples the other end of the rod to the apex of speaker cone 6. The arrangement converts lateral movement of the stylus due to the record groove modulation to reciprocating movement of the speaker cone apex. A return arm actuated by a pull string for winding the spring motor acts to lift the pick-up arm and return same to a start position and during operation a cam portion of the return arm slides on a stop 226 on the arm to stabilize the arm during playback. The two annular records, which can be integral with their turntables rotate at different levels and the arm 104 is provided adjacent the stylus with a cam portion which guides the stylus from the end of a track on the upper outer record to the start of a track on the inner lower record. The cord reel for the spring motor and the spring arbour are connected to the inner turntable which is turn is coupled by a pinion 144 to the outer turntable such that during winding of the spring motor the inner turntable can rotate relative to the outer, but during drive by the spring motor the turntables are coupled to rotate together. The outer turntable is belt coupled to a governor.

Title: Improvements in or relating to Video Telephone Systems
Inventor: HOLLOWAY DENNIS GODSON

Abstract: 1,173,918. Video-telephonesystem. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. 4 Dec., 1967 [5 Dec., 1966], No. 54415/66. Heading H4F. In a video-telephone system arranged to establish simultaneous connection, i.e. video conference facilities, between more than two subscribers, e.g. four subscribers A, B, C and D, Fig. 4, each subscriber has a television camera (transmitter) and a television receiver connected to the exchange, and each receiver is arranged to display the pictures generated by the cameras of all four subscribers, e.g. each subscriber is pictured in a different corner of the display screen of each reciever. To achieve this display the speed of both the line scan and field scan is doubled for each camera as compared with the scanning speeds of the receivers, and the resulting waveforms are suitable blanked so that only a quarter of the total output from each camera is effective, the blanking being such that the four waveforms may be combined without interference, Fig. 3 (not shown). In addition to synchronizing the four cameras, correction must be applied for phase differences due to differences in the lengths of the transmission paths between the cameras and the exchange where the combination of the picture signals takes place. In the exchange, common timing pulses from a generator G are fed via a summing point S to the scanning circuits of the receivers A, B, C and D. Regenerated pulses from these receivers are used to operate the scanning circuits of their associated transmitters, the picture signals from which are fed to the summing point S. To correct the resulting phase errors due to the different transmission paths, a variable pulse delay arrangement is added between each receiver and transmitter, which is arranged to delay the scanning pulses so that the picture signals from the transmitters arrive at the summing point S in phase with the original pulses from generator G. To achieve this, each delay is equal to the time of one line scanning period minus the time delay due to the respective transmission path in both directions. The timing pulses may be generated at the transmitter of one of the subscribers, e.g. the originator of the conference. The delays may be arranged to be equal to a complete number of line-scanning periods in a permanently set-up system. A separate signal which provides the delay correction information may be transmitted from each subscriber to the exchange during the vertical flyback period. Two pairs of subscribers respectively associated with local exchanges may be connected by a long trunk route, Fig. 5 (not shown), in which case the signal time delay in the trunk route is arranged to be equal to a whole number of line-scanning periods.

Title: Method of and apparatus for joining thermoplastic material
IPC: B29C65/34
Filed: 1967-12-11
Abstract: 1,206,458. Seaming non-metallic sheet material. CYKLOP GESELLSCHAFT EMIL HOFFMANN K.G. 11 Dec., 1967 [2 Feb., 1967], No. 56271/67. Heading B5K. Two end portions 15, 16 of a band of thermoplastic material are joined by inserting a wire mesh element 29 between the portions 15, 16 at the desired location of the joint, heating the element 29 and pressing the portions 15, 16 together with the element 29 interposed therebetween, the element 29 remaining in the band when the joint has been formed. Apparatus for tensioning and joining the ends 15, 16 of a thermoplastic strap passing around an article comprises devices 13, 14 pivoted on a cheek-piece 2 to clamp the ends 15, 16 against a plate 11. The end 15 is guided over an inclined surface 17 on a wedge 19 formed with a knife edge 18<SP>1</SP> to co-operate with a cutting edge 20 on a punch 21 pivoted on the plate 11 and formed with a recess 22. The face 23 of the punch to contact the end 15 has a polytetrafluoroethylene cover 24 and the upper face of the plate 11 is coated with polytetrafluoroethylene. Guides 26 are arranged to extend longitudinally of a channel 25 in which the end 16 is positioned. Electrical contacts 27, 28 slide in the guides 26 and rest upon the end 16. In operation, the ends 15, 16 are positioned in the apparatus as shown in Fig. 1. A roller 18 is rotated in the direction 30 to tension the end 15 and the pull applied to the end 16 causes the device 14 to clamp this end. When the drive to the roller 18 is arrested, the end 15 slips back a short distance and is clamped by the device 13. The wire mesh element 29 is placed on the contacts 27, 28 and the punch 21 is depressed so that the part 15a of the end 15 is severed by the edges 18<SP>1</SP>, 20. Current is supplied to the contacts 27, 28 and when the mesh 29 has become heated to soften the thermoplastic material of the ends 15, 16, the contacts 27, 28 are drawn apart and a heavier pressure is applied to the punch 21 so that the joint is formed. After release of the devices 13, 14, the apparatus is withdrawn sideways from the strap. In another embodiment, Fig. 3 (not shown), the guides (26) extend transversely of the ends (15), (16) and the contacts (27<SP>1</SP>), (28<SP>1</SP>) are disposed along the longitudinal edges thereof so as to be adjustable for different widths of strap. Heavy pressure is applied to the punch immediately after tensioning the strap since it is not necessary to draw the contacts apart after heating the mesh (29). The punch may be provided additionally with cutting edges along the sides thereof to sever any parts of the mesh projecting from the joint. In a further embodiment (not shown), the wire mesh is heated by inducing a current therein, e.g. by applying current to the punch.

Abstract: 1,209,949. Copying apparatus. MEOPTA NARODNI PODNIK. Dec.12, 1967 [Dec. 19, 1966], No. 56358/67. Heading G2A. The light source in the lamp housing of a copying apparatus can be movably adjusted along the optical axis by means operable from outside the head, its position being indicated by means also outside the head. In the arrangement shown, three objective lenses of different focal lengths (105, 165, and 210 mm) are available, these being marked on an indicator plate 25 attached to the outside of the wall 1 of the lamp housing. This has three apertures 13, 13<SP>1</SP>, 13<SP>11</SP> in register with the three markings on plate 25. A slide 3, movable in the direction S by a handle 9, has three cut-outs 34, 34<SP>1</SP>, 34<SP>11</SP> in a cascade arrangement. When one of these cutouts is in alignment with one of the markings on plate 25, this will be illuminated by light within the housing, thus indicating which objective lens is in the working position. On the outside of the wall 1 a transparent disc 2 is mounted on a spindle 21, the disc carrying three magnification scales 22, 23, 24, one corresponding to each objective. A further set of cascaded cut-outs 33, 33<SP>1</SP>, 33<SP>11</SP> on slide 3 move in register with these three scales. The lamp 4 is mounted in a socket 41 on an arm 42 of a carrier 43 (see also Fig. 2 not shown), the carrier being slidable along a guide rod 44. A pin on the carrier engages in a helical groove 451 in a further guide rod 45, so that as rod 45 is rotated by means of a knob 8 outside the housing, the lamp moves in the direction S, so varying the amount of light passing through the objective. The carrier 43 is also connected to the spindle 21 by a belt 47, so that as the lamp moves, disc 2 rotates. As slide 3 is moved so that one of the cut-outs 34, 34<SP>1</SP>, 34<SP>11</SP> indicates which lens is in use, the corresponding cut-out 33, 33<SP>1</SP> or 33<SP>11</SP> is set behind an aperture 12, 12<SP>1</SP> or 12<SP>11</SP>, so that light from within the housing illuminates the scale corresponding to that particular lens. The mounting column of the lamp housing carries a series of calibrations giving the value of the magnification for the particular lens in use and for the height at which the housing is set, so as to provide optimum uniformity of illumination. Movement of the lamp, and hence of disc 2, is then adjusted until the reading of the appropriate scale on the disc, as seen in register with the cut-out in slide 3, corresponds with the calibration figure read off on the mounting column.

Abstract: 1,235,809. Train control system. GENERAL SIGNAL CORP. 3 Dec., 1969 [6 Dec., 1968], No. 59012/69. Heading B7N. [Also in Division G3] In an arrangement for automatically controlling a train 10 to a halt at station platform 11, pick up coils 16 on the train receive a track signal from unit 13 having a frequency which is a function of the distance to stop and this signal is applied with a signal from axle driven generator 14, having a frequency proportional to train speed, to a control circuit providing an output E for controlling train brake and speed control equipment 17. The track between unit 13 and the leading axle of the train forms a variable inductive element which controls the frequency of an oscillator circuit in the unit, which thus supplies a signal to the track rails having a frequency inversely proportional to the root of the distance to stop. A voltage analogue of this signal is provided by unit 18 and supplied to a multiplier 20 which receives as second input an analogue of the speed signal supplied from generator 14. If the train is decelerating correctly the product signal should be constant and to obtain this condition the product signal is applied with a fixed voltage K2 to a difference circuit 21 which supplies via an integrator circuit 22 the controlling error voltage E. By connecting the unit 13 to the rails at the point braking is to commence and by providing the coils 16 at the end of the train, the frequency of the picked up signal can be directly related to the distance to go.
